This pic has two diferent files. One ramped and moved in the Z as it should and the other didn't move in Z untill the rams were done.??? I cant see the diference????

The code looks correct in that you are receiving Z movements on each line in which the machine should be interpreting those to move the axis' at the same time. Is this the way that all of you 3 axis movements generally look? Is this how you would hand program the machine if you had to or is there a variable that needs to be called out in the post that is not there that would trigger all your axis' to function at the same time? Is this type of movement supported by the machine?

I'm sort of lost... The one on the right worked... left didn't. Only diference is left is a tight circle/oval and right is a large circle....
here is what the Control needs.... and seems to have....

G02 = Circular interpolation (CW)
Format: X__Y__I__J__ I,J are relative distance from start to center.
Incremental Z can be added for helical designs. Important: The G02/03
commands must be written with X value Y Value I Value and J value on every
line for it to work properly. If you place a Z coordinate on the same line,
that will command the toolpath to run a helical program with X Y and Z running at the
same time.
G03 = Circular interpolation (CCW)

I have some video that I think I can load here... Think I can... Is the key phrase....

The one thing I dont get.... At the end of the spiral ramp to depth.... What made it go to the depth??? IE it finished the ramp to the depth needed (middle line N70) and then plunged to that depth and went along to mill that out.Line N70 is the same as every one of them above it... and the moves to remove the material at that depth doesnt have a Z value in them.
The last plunge or third in case fould the bit and it couldn't remove matterial and snapped. That being my fault for not stopping it. It did ok before so I really wanted to see if it cut through the teeth again.

Hold the show a sec... Just watched the video and I think I'm displaying the left side and right... wrong.. I have to check some stuff... But think those are pocket profiles, and the one messing up is the high speed pocket....

[Martin 007]

OK yes I most certainly did !! The picture above shows code for the inner circle which is just BobCads pocketing feature. Because the HighSpeed feature wouldn't generate code for them. The code where it is not going down in Z (below) is the Highspeed feature or outside of the portion of the part... So basically the HighSpeed Feature is not working at all.!! I'm going to see if I can find another mill and do it again without HSP...
Sorry for the mix up... well fooled myself as well.... Here is the code from the HSP ramp down without Z moving....

So there ya have it... going to look at the cut through the teeth and I bet there is a missing Z in the line.... that should bring it to clearence before its rapid over....

[Martin 007]

OK I just posted out using High Speed pocketing and then did it in basic pocket. It seems that the HSP feature is ignoring BobCads settings such as feeds and speeds limits and such. Why it doesnt post Z codes on each line as the post for my machine tells it to do... I think.... Basic does it.
Ran both through Predater Editor.... HSP mill time... 19:54 Basic pocket Mill time 07:47
There is definately something wrong here... or its not so high speed....

OK so I have no more 1/4 mills.... So I going to change to 5/16 and finish with 3/16 using the basic pocket feature and send it to the machine... Will let you all know.
Thanks for your time with my bumbling around....
